From: Suppression of X-ray-induced dissociation of H2O molecules in dense ice under pressure
Microphotographs of H2O in diamond anvil cells with reflected and transmitted illumination before (left panels) and after (right panels) 10-keV X-ray irradiation at (a) 7.5, (b) 21 and (c) 39 GPa pressures. The X-ray is incident from the upper left in (a), the left (b) and the lower left in (c). The color where the incident X-ray passed changed at 7.5 and 21 GPa whereas there was almost no change observed at 39 GPa. The scale bar is 50 μm.
